C++ Move Semantics - The Complete Guide

Move semantics, introduced with C++11, has become a hallmark of modern C++ programming. However, it also complicates the language in many ways. After several years of support for move semantics, experienced programmers still struggle with all the details. Even for trivial classes, style guides give conflicting or inappropriate advice on how to benefit from move semantics.
Time to explain all aspects of C++ move semantics in detail.
This book teaches C++ move semantics. Starting from the basic principles, it motivates and explains all the corner cases of move semantics so that as a programmer, you can use move semantics correctly. The book is valuable for those who are just starting to learn about move semantics and is essential for those who are using it already.
You will learn:
As usual for books by Nicolai
Josuttis, the focus lies on the application of the features described
in practice. Compelling examples and useful background information help
you to understand and improve code, from trivial classes up to generic
foundation libraries and frameworks.
Nicolai M. Josuttis is well known in the programming community for his authoritative books and talks. For more than 20 years he is a member of the C++ Standard Committee. He is the (co-)author of several worldwide best-sellers, including
"I thought I understood
move semantics but I didn't really! I learned a lot in your book."
"This is the book Ive
needed for a long time.
"Sometimes I think I have a better grasp on entanglement and quantum teleportation than I do in some weird C++ move semantics. To paraphrase Feynman: If you think you understand C++ move semantics, you do not understand C++ move semantics. Read this book." Victor Ciura
